AIRRANE for Nitrogen

The membranes are produced in the form of hollow fibres. Gas separation membranes work on the principle of selective permeation through a membrane surface. The difference between the partial pressure of the gas on the internal side of the membrane and external side. If greater this difference, the greater the permeation of gas through the membrane.

The permeation rate of each gas depends on its diffusion rate in the membrane. Gases with higher diffusion rate and lower molecular size penetrate the membrane faster than large, lesser diffusion gases. nitrogen gas membrane system

Each membrane module contains millions of hollow fibres. The high density of the fibre bundle provides a vast membrane surface area through which the air components permeate with different velocities. Nitrogen has a lower permeation velocity than oxygen, CO2 and water vapour. Hence these gases pass through the membrane and vented to atmosphere at the safe location (particular attention shall be given to the fact that the vented gas to atmosphere is enriched with oxygen). Only nitrogen is come out of the membrane.

Advantages:

· Proven technology also for off-shore applications

· Simple and very reliable operation

· Lower weight, footprint and noise compared to other technologies

· Easy to operate and maintain

· Future scale-up of membranes capacity is easy, only additional membrane banks are needed

Disadvantage:

· Higher feed air consumption compared to other technologies

· Higher electrical consumption compared with Pressure Swing Adsorption for inlet air heating

· Very sensitive to water, oil droplets and impurities

· Irreversible fouling and easy breakage are the main problems concerning hollow fibre filtration.

The membranes are more likely to break when under high strain compared to other methods of nitrogen generation gas separation membrane
